Score an Azure subscription across reliability, cost, security and operations, and see which pillar to fix first.
Each pillar is scored from coverage percentages you can pull from Azure Policy, Defender for Cloud, Advisor and Azure Monitor, then combined with reliability and security carrying the heaviest weight. Orphaned spend is penalised sharply because it is pure waste with no offsetting benefit, so even a few percent drags the cost pillar down hard. A single score makes an Azure estate comparable over time and across subscriptions, and the weakest-pillar output turns that score into one concrete next action instead of a dashboard nobody reads.
Azure Health Score
score = reliability × 0.30 + security × 0.30 + cost × 0.20 + operations × 0.20, where each pillar is a weighted blend of its coverage inputs and orphaned spend is penalised at four points per percent.

This calculator takes 8 inputs: Production workloads that are zone redundant, Production resources with a tested backup, Steady-state compute covered by reservations, Spend on orphaned or idle resources, Azure Policy compliance, Resources covered by Defender for Cloud, Resources sending logs and metrics, Alerts that lead to a real action. The pre-filled defaults are a realistic starting point — replace them with figures from your own environment for a result you can act on.
